Diffuse large B-cell lymphoma (extranodal) of maxillary buccal vestibule.

Lymphomas are the group of neoplasms originating from lymphoreticular system mainly from lymph nodes, among them up to 40% of non-Hodgkin's lymphomas present extra nodally. In oral cavity, lymphomas are least common and account for 3-5% of all malignancies, presenting mainly in older age groups with male predominance. According to Revised European-American Lymphoma classification, among B-cell and T-cell subtypes of non-Hodgkin's lymphomas, diffuse large B-cell lymphoma (DLBCL) is the most common, characterized by diffuse proliferation of large neoplastic B lymphoid cells.

Evaluation of Podoplanin in Oral Leukoplakia and Oral Squamous Cell Carcinoma.

Background. Recent studies have demonstrated that podoplanin was expressed in some dysplastic lesions adjacent to primary oral cancers suggesting that podoplanin expression may occur in early oral tumorigenesis and lymphangiogenesis and therefore is related to tumor growth. The purpose of this study is to determine the role of podoplanin as a biomarker for cancer risk assessment in oral leukoplakia and correlation of podoplanin expression with grades of oral squamous cell carcinoma (OSCC).

Invasive cervical resorption: a review.

Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unless pulpal or periodontal infection supervenes.

Quantitative estimation of Serum Fibrinogen Degradation Product levels in Oral Premalignant and Malignant lesions.

Background: A specific association between cancer and the hemostatic system has been recognized for decades. Fibrinogen degradation product (FDP) is one of the factors, which opposes coagulation causing fibrinolysis. The mechanism of fibrinolysis can be used by the malignant cells to facilitate invasion into surrounding tissues and metastases to distant organs by breaking the fibrin barrier.

Solitary angiokeratoma of oral mucosa: a rare presentation.

Solitary angiokeratoma of oral mucosa is rare entity. The term Angiokeratoma is used to refer to several lesions, whose common denominator is the presence of dilated blood vessels in association with epidermal hyperplasia. Mucosal involvement, including oral cavity is occasionally found either as a component of the systemic variety, cutaneous involvement or isolated oral involvement.
